Data taken without any reason

I logged a complain on the 9th June 2019 about my data that was taken back. Firstly I was billed incorrectly, which was corrected but my data was taken. I have had my contract for 21 months without any problems. Up to date this query has not yet been resolved. Cell C commits itself to resolve issues within 2 working days. The month is going for its 3rd week, when will I be in a position to use data that Im paying for, but are unable to do so.
